Smart Door Window Sensor with App Alert, Wireless Magnetic Alarm for Home Security

【Magnetic Sensor Technology – Instant Open/Close Detection】 The sensor uses high-sensitivity magnetic induction to detect door and window openings instantly. When the door or window is opened, the magnet separates from the main unit and triggers an immediate response. No delays, no missed alerts – your home is protected the moment an entry point is breached. 【Smartphone App Alerts – Stay Informed from Anywhere】 Connect the sensor to your home Wi-Fi via the mobile App and receive real-time push notifications whenever a door or window is opened. Whether you‘re at work, on holiday, or just in another room, you’ll always know what‘s happening at home. Perfect for monitoring main doors, windows, cabinets, and even safes. 【Simple Peel-and-Stick Installation – No Tools Required】 Installing the sensor takes just seconds. Clean the mounting surface, peel off the 3M adhesive backing, and stick the main unit to the door frame and the magnet to the door itself. No screws, no drilling, no professional installation. The sleek minimalist design blends discreetly into any home décor. 【Ultra-Low Power Consumption – Long Battery Life】】 Designed for long-term use with minimal maintenance, this sensor features ultra-low power consumption for extended battery life. The hidden LED indicator provides clear status updates without being intrusive. You’ll receive low-battery alerts through the App, so you’ll always know when it‘s time for a replacement. 【Wide Application – Use on Doors, Windows, Cabinets & Safes】】 Versatile and reliable, this sensor can be installed on a wide range of entry points: front doors, back doors, windows, sliding doors, cabinets, drawers, and even safes.
